DNS Security (DNSSEC) DNSKEY Algorithm IANA Registry Updates
Abstract
The DNS Security Extensions (DNSSEC) require the use of cryptographic
algorithm suites for generating digital signatures over DNS data.
The algorithms specified for use with DNSSEC are reflected in an
IANA-maintained registry. This document presents a set of changes
for some entries of the registry.

The Domain Name System (DNS) Security Extensions (DNSSEC, defined by
[RFC4033], [RFC4034], [RFC4035], [RFC4509], [RFC5155], and [RFC5702])
use digital signatures over DNS data to provide source authentication
and integrity protection. DNSSEC uses an IANA registry to list codes
for digital signature algorithms (consisting of an asymmetric
cryptographic algorithm and a one-way hash function).
This document updates a set of entries in the IANA registry titled
"DNS Security (DNSSEC) Algorithm Numbers". These updated entries are
given in Section 2.2 below. This list includes changes to selected
entries originally set aside for future algorithm specification that
did not occur. These three entries are changed to "Reserved" to
avoid potential conflicts with older implementations. This document
also brings the list of references for entries up to date.
There are auxiliary sub-registries related to the DNS Security
(DNSSEC) Algorithm Numbers registry that deal with various Diffie-
Hellman parameters used with DNSSEC. These registry tables are not
altered by this document.
2. The DNS Security Algorithm Numbers Sub-Registry
The DNS Security Algorithm Numbers sub-registry (part of the Domain
Name System Security (DNSSEC) Algorithm Numbers registry) contains a
set of entries that contain errors. There are additional differences
to entries that are described in Section 2.1, and the complete list
of changed registry entries is in Section 2.2.
2.1. Updates and Additions
This document updates three entries in the Domain Name System
Security (DNSSEC) Algorithm Numbers registry:
The description for assignment number 4 is changed to "Reserved".
The description for assignment number 9 is changed to "Reserved".
